AI Technical Summary

Benefits of technology

This patent is about a new lubricant composition that can be used in drilling operations. The composition includes a base oil composition with water and a friction-reducing composition made up of certain compounds. The friction-reducing composition helps to reduce the friction experienced during drilling, which can improve the operation. The patent also describes methods of making and using the lubricant composition. The technical effect of this invention is to provide a better lubricant composition for drilling operations, which can help to improve the efficiency and performance of drilling operations.

Problems solved by technology

Many formations present difficulties for drilling.
For example, the horizontal displacement that occurs in extended reach drilling (ERD) is often limited by torque and drag losses due to friction.

example 1

[0110]In Example 1, a base oil composition comprising about 210 g Escsaid™ 110, about 8.0 g VG Plus™, and about 7 g of lime are added and mixed for about 5 min. About 9.0 g of MegaMul™ is added to the resulting mixture followed by about 5 min. of further mixing. About 18.5 g calcium chloride is mixed with about 50 ml of water and added to the mixture, followed by about 225 g of barite weighting agent. The combination is mixed for about 10 min. before addition of about 6.0 grams of Versitrol M™ followed by an additional 5 min. of mixing. Thereafter, about 45.0 g of Rev Dust™ is added followed by 10 min. of mixing. The base oil composition is hot aged for about 16 hours at a temperature of about 120° C. The coefficient of friction (CoF) of the base oil composition is measured as a baseline and reported in Table I.

example 2

[0111]In Example 2, Example 1 is substantially repeated, except that the composition comprises about 97 wt % of composition of Example 1 and about 3 wt % of a conventional friction reducing agent available under the tradename Ultralube II, available from Integrity Industries, Inc., Kingsville, Tex., USA. The mixture is covered and heated to about 60° C. while being mixed for about 60 min. The sample is cooled at about 25° C. for 16 hrs. The cooled sample is mixed for about 30 min. at about 4000 rpm. The coefficient of friction (CoF) of the sample is reported in Table I.

example 3

[0112]In Example 3, Example 2 is substantially repeated, except that the composition comprises about 97 wt % of composition of Example 1 and about 3 wt % octadecyl thioglycerol. The coefficient of friction (CoF) of the base oil composition and additive package is reported in Table I.

Abstract

Lubricant compositions having at least one base oil composition including about 1.0 to about 15.0 wt % water, and a friction-reducing composition including a glycerol or thioglycerol compositions are described. Methods for making such lubricant compositions and methods of drilling using such lubricant compositions are also described.
